To all w t may concern:

Be it known that l, donn Gr. Shame, a citizen of the United States, and a resident of the city of Ripon,

/ du Lac and State of Wisconsin, have invented certain new and useful llmprovements in a Control Mechanism for W ash Wringers; and ll do hereby declare that the iollowin is a full, clear, and exact descri t@ tion of t e same reference being had to t e accompanying drawings, .and to the numerals of reference marked thereon, which form a part'of this specification. e

llt is an object of this invention to prow vide an improved mechanism for driving the wringer attached to a washing machine.

It is a further object of this invention to provide an improved way of supporting the wringer in any of a number of posi- @t tions in relation to the machine.

It is afurther object of this invention to driving the Wringer which shall be made of few parts and readily and easily assembled.

w It is a further object of this invention to provide a direction changing clutch of a form that shall enable the handle controlling the same to be so easily accessible.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention (in a preferred form) is 85 illustrated in the drawings and hereinafter more fully described.

Figure 6 is a section upon the line 6-6 of Figure 5.

Figure 7 is a top plan'view of the lower part of the housing, certain parts being shown in section.

upon the line 4 4 in the county of Fond provide a housing for the mechanismv positioned that it is- As shown on the drawings:

he washing machinek cabinet 10 is provided with a bracket 11 which supports the. vertical cylindrical housing 12 for enclosing a shaft 13 at the lower end of which .is mounted a bevelA gear 14:. 'llhi's meshes. with a bevel gear 15 on a horizontal shaft projecting through the wall or the washing machine cabinet. 'llhe two bevel gears are enclosed within a triangular housing which is integral with the bracket 11.

The upper end of the cylindrical housing 12 is provided with a horizontal table 17 the edges of which are flanged as shown at 18 to provide a circular saucer-shaped seat for receiving the circular foot 19 of a rotatable casting 20 which has a column extending from the foot 19 to the body ol the casting. This column -includes a cylindrical part 21 and ribs or flanges 22.

The column also has a projecting part siimilar to the ribs but of greater cross section as shown at 23. This part is made hollow, and the bore thereof as shown at 24 is cylindrical in order to house a spring 25 and a plunger 26. A slot 27 is provided in the outer side of the projection 23 to accommodate the stem 28 of anoperating pin having a head 29. The lower` end of the plunger 26 has a projecting end 30 adapted to enter any of a number of holes 31 provided in the table 17 and forming a circular series surrounding theshaft 13. In the form illustrated only two of these holes are shown, but an desired number may be provided to make 1t possible to secure the Wringer in any desired number of positions.

Above the column 21,-the casting 20 is provided with a hemispherical bowl 32 for housing the" manually controlled motion reversing clutch for the wringer. At one side this bowl is provided with a projection 33 which forms the lower half o a bearing for the shaft 42 which drives the wringer. The lower half of a second bearing for this shaft is provided on the opposite side of the bowl at 34. Beyond the half-beari`ng 34 the casing 20 is provided with a larger lxalfl-bearing 35, to receive a hollow sleeve 36 "which is provided with a square socket for the rece tion of the square end of the wringer sha 37.

The housing of the clutch is completed by a supplemental casing 38 which has a hemispherical cap 39 to cover the upper part liti ' V-shaped projection of the clutch. At one side the cap 39 is .rovided with a projection 40 to cooperate with the projection 33 and make a bearing for one end of the shaft 42. At the other side of the cap 39, the casting 38 is provided with a semi-cylindricalV part 43 which affords a half bearing to cooperate with the half bearing 34 for thev shaft 42 and a larger half bearin to cooperate withV the half bearing 35 for ie sleeve 36. Bolts 44 secure the two halves of the housing together in the usual way.

The vertical tube afforded by the columnar parts 12 and 21 is lined throughout its length with a tubular lining 50 which is provided at suitable intervals with bushings 51 to guide and support the shaft 13. Pinned to the upper end 0f the shaft 13 and bearing against the upper end of the lining 5() is a bevel gear 52, which meshes with either one of two bevel-gears 53 and 54. These gears are pinned to the shaft 42 and they and the shaft move together bothr in rotatingjmd in lengthwise travel.

o provide for eccentric disk 57 is positioned between the gears 53 and 54, and bears against the inner faces of them. This is called an eccentric disk because it is 'eccentrically connected to a short shaft 60. The shaft 60 is guided and supported in a boss 61 formed in the upper ge part of the hemisphere 39. The upper e of this boss is provided with il-shaped notches 62, preferably three in number, although more maybe used. Pinned to the upper end of the shaft 60 is a handle 63. The hub of this handle is provided with a 64 which' is adapted to the notches 62. The shaft 60 is yieldin ly held in position by. the spring 65. ne end of this spring bears against the under face of the boss 61 and the other end of the spring bears against the disk 57 in the operation of the device:

Moving the handle 63 will cause the projection 64 to slide out of the notch 62, move ing the shaft 60 a short distance longitudinally and thus compressing the spring 65. When the handle 63 has been rotated far enough so that the projection is opposite the next notch 62 the spring 65 will expand bringing the shaft 60 and disk 5 7 to the same height that they originally occupied and'the projection into the new notch. This introduces a certain resistance to the motion of the handle 63 and the operator is thus enabled to readily select the correct position of this handle.

1n one of these positions the disk 57 will have its larger side toward the projections 33 and 40. A t a position 90 removed from this the disk will extend equally on the two sides ofthe shaft 60 toward the projection 33 and toward the bearing 34. In the posifit in any one of this lengthwise travel, an l 13 as an axls.

Megeve tion 180o position the larger side of the disk will be toward the bearing 34. Since the gears 53 and 54 contact with the disk 57, they will move from the position illustrated in Fig. 5 which corresponds to the first described position of the handle to a position in which neither the gear 53 nor the gear with the gear 52 which corresponds to the second described position fof the handle. When the handle 63 is moved further the gears 53 and 54 will come to a position which is the opposite limit of their travel and in which the gear 54 will mesh with they gear 52 and the gear 53 will be out of mesh. This corresponds to the last described position of the handle. Since the shaft 13 and the gear 52 are continually driven in the same direction the shifting of the shaft 42 to bring one or the other of the gears thereon'into mesh with the gear 52` will reverse the wringer as is well known in the art. When this handle 63 is in an intermediate position so that neither of the gears 53 and 54 mesh with the gear 52 the wringer will not be driven. Thus rotation of the wringer is completely controlled by position of the handle 63. The shaft 42 moves longitudinally as the gears, 53 and'54 shift and the sleeve 36 moves with it. In the illustrated position the end of the sleeve is substantially flush with the face of the castings 20 and 38 while the end of the shaft 37 does not reach to the bottom of the socket. In the opposite position the sleeve 36 is rotruded and the end of shaft 42 is very c ose to the end of the shaft 37.

The position of the wrnger may betered by rotating the housing ma e u of the two castings 2O and 38 about the s aft To do this the head 29 is removed from the first described 54 meshes' al-V first raised so that the end 30 of the langer n 26 is no longer seated in a hole 31. e castings are then free to rotate, carrying the wringer with them. When the rotation has proceeded so far that the position of the wringer corresponds with the next hole 31, the spring 25 causes the end 30 to sna into this hole and the wrin er is locked 1n the new position. Two-ho es 31 are provided, one corresponding to a position where the clothes are wrung either into or out of the tub, depending upon the position of the handle 63, and the other corresponding to a position inwhich the clothes are wrung from one receptacle to another, both outside the tub. Obviously other positions may be used if desired by increasing the' number of holes 31.

I am aware that numerous details of construction may be varied through ya wide range withoutdeparting from the principles of my invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
